S82.455D Nondisplaced comminuted fracture of shaft of left fibula, subsequent encounter for closed fracture with routine healing

Name of the Condition

• Nondisplaced comminuted fracture of shaft of left fibula, subsequent encounter for closed fracture with routine healing
• ICD-10-CM Code: S82.455D

Summary

A nondisplaced comminuted fracture of the shaft of the left fibula is a bone injury where the fibula (the smaller lower leg bone) is broken into multiple pieces but remains in its normal anatomical alignment. This code applies to a subsequent encounter for a closed fracture (no skin penetration) with routine healing, indicating the fracture is progressing as expected without complications.

Causes

This fracture typically results from direct trauma to the leg, such as a fall, sports injury, or accident, which causes the bone to shatter into several pieces without displacement. High-impact forces or twisting motions are common mechanisms.

Risk Factors

• Participation in high-impact sports or activities
• Osteoporosis or other bone-weakening conditions
• Advanced age, which may reduce bone density
• Previous leg injuries or surgeries

Symptoms

• Pain and tenderness along the fibula
• Swelling and bruising around the lower leg
• Difficulty bearing weight on the affected leg
• Possible deformity if alignment is compromised

Diagnosis

Diagnosis involves a physical examination to assess tenderness, swelling, and deformity. Imaging tests, such as X-rays, are typically used to confirm the fracture and evaluate healing progress. Clinical documentation should reflect routine healing without complications.

Treatment Options

• Immobilization using a cast or brace to maintain alignment
• Pain management with medications
• Physical therapy to restore mobility and strength after immobilization
• Monitoring for signs of delayed healing or complications

Prognosis and Follow-Up

With routine healing, most nondisplaced fractures heal within 6–8 weeks. Follow-up appointments monitor progress, and physical therapy may be recommended to restore function. Full recovery is expected with proper care.

Complications

• Delayed healing or nonunion
• Malunion (improper alignment)
• Nerve or vascular damage (rare)
• Chronic pain or stiffness

Lifestyle & Prevention

• Use protective gear during high-risk activities
• Maintain bone health through diet and exercise
• Avoid repetitive high-impact stress on the legs
• Address underlying bone conditions like osteoporosis

When to Seek Professional Help

Seek care if symptoms worsen, new swelling or pain occurs, or there is difficulty bearing weight. Signs of infection (e.g., redness, fever) or delayed healing also require prompt evaluation.

Tips for Medical Coders

Document the fracture as closed with routine healing to support this code. Include details on alignment, healing status, and absence of complications. Ensure the encounter is coded as subsequent (not initial) and specify the left fibula shaft location.
